Description

Technical Field

[0001] This utility model relates to the field of feeding equipment, and in particular to an automatic material distribution and conveying system. Background Technology

[0002] Bars and tubes are materials frequently used in industrial production. They are typically transported to the production site as long workpieces, and then cut to the required length using cutting equipment. The cutting process requires conveying the long workpieces. To improve feeding efficiency and accuracy, and to reduce labor costs, many companies now use automated feeding and conveying devices to feed the long workpieces one by one into the cutting equipment for fixed-length cutting.

[0003] For example, Chinese utility model patent CN216097767U discloses an automatic feeding device for a lathe, which includes a storage rack and a feeding rack. The storage rack is connected to the feeding rack, and a retractable stop assembly is provided at the connection between the storage rack and the feeding rack. The end of the feeding rack away from the storage rack is provided with a stop mechanism that can slide along the feeding rack and a lifting assembly that plays a lifting role. The stop mechanism and the lifting assembly are arranged side by side and correspond to each other. When feeding is required, the position of the stop baffle in the stop mechanism is first adjusted according to the thickness of the anchor bolts. Then, the stop assembly retracts downward, and the workpiece on the storage rack rolls along the feeding rack. When it rolls to the stop baffle, it stops moving. Then, the lifting cylinder of the lifting assembly pushes upward, driving the lifting plate to move upward, picking up the anchor bolt from the stop baffle and transferring it to the subsequent processing device, thus completing the feeding operation.

[0004] However, the aforementioned automatic feeding device is not suitable for conveying long workpieces with a diameter of 200mm or more. A single long workpiece can weigh over 4 tons. When several long workpieces roll along the feeding frame to the stop baffle, they will exert a large impact force on the stop baffle and even the entire stop mechanism, which can easily damage the entire stop mechanism. Furthermore, when several long workpieces are on the feeding frame, due to the inclined setting of the feeding frame, the workpieces tend to roll towards the stop baffle, causing them to be squeezed together. When the picking component lifts a particular long workpiece, it needs to overcome not only the weight of the workpiece itself but also the squeezing and frictional forces from other long workpieces. This makes lifting difficult and can easily damage the picking component.

[0005] In addition, in order to ensure that the cutting surface is a vertical plane, the top surface of the feeding device in the prior art is kept on the same horizontal plane as the top surface of the cutting platform of the cutting device. However, since long workpieces may bend during production and transportation, during transportation, the bottom surface of the end of the long workpiece may be lower than the workpiece bearing surface of the cutting platform, which makes it impossible for the end of the long workpiece to enter the cutting platform smoothly and thus cannot achieve automatic feeding.

[0006] Therefore, it is necessary to provide a technical solution to address the above problems. Utility Model Content

[0007] The purpose of this invention is to provide an automatic material sorting and conveying system that can solve the technical problems in the prior art where the automatic material sorting and conveying device is prone to damage to the stop mechanism and lifting mechanism when conveying large-diameter long materials, and is unable to smoothly convey long materials that have been bent to the cutting platform.

[0008] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an automatic material feeding and conveying system, including a control mechanism and a frame, wherein the two sides of the frame are the feeding side and the discharging side, respectively; multiple bearing rods and multiple lifting rods are spaced apart along the length direction on the frame; multiple first stop rods, multiple eccentric conveying roller mechanisms, and at least one sensor are spaced apart along the length direction on the discharging side of the frame; the end of each lifting rod near the discharging side and the end of each first stop rod away from the discharging side are respectively hinged to the frame; the multiple lifting rods are connected to a first driving mechanism, which drives the multiple lifting rods to move around their hinged positions. The first stop rods are rotated; a plurality of first stop rods are connected to a second drive mechanism, which drives the plurality of first stop rods to rotate about their hinged positions; each of the eccentric conveying roller mechanisms has a second stop rod fixedly provided at one end near the feed side; the plurality of eccentric conveying roller mechanisms are connected to a third drive mechanism, which drives the eccentric conveying roller mechanism to rotate, thereby causing the second stop rod to swing between the avoidance position and the blocking position; along the direction from the feed side to the discharge side, the bearing rod sequentially includes a first horizontal section, an inclined section and a second horizontal section, the horizontal height of the second horizontal section is higher than the horizontal height of the first horizontal section, wherein a blocking block is provided at one end of the second horizontal section near the inclined section.

[0009] Furthermore, when both the lifting rod and the first stop rod are rotated and lifted, an angle is formed between the lifting rod and the first stop rod, and the vertex of the angle is located on the side of the stop block closer to the discharge side.

[0010] Furthermore, the eccentric conveying roller mechanism includes a rotating shaft, two support seats, two eccentric bearings, and a roller. The two support seats are spaced apart on the discharge side of the frame. The two ends of the rotating shaft are rotatably mounted in the two support seats, and one end of the rotating shaft passes through the corresponding support seat and is driven to connect with the third driving mechanism. The two eccentric bearings are fixedly mounted on the rotating shaft and located between the two support seats. The two ends of the roller are respectively sleeved on the two eccentric bearings.

[0011] Furthermore, the second stop is fixedly connected to one end of the rotating shaft near the feed side and is located between the roller and the support seat; when the second stop is in the material blocking position, the top of the roller is at its highest position, and when the second stop is in the clearance position, the top of the roller is at its lowest position.

[0012] Furthermore, the third drive mechanism includes a first cylinder and a slide rod connected to the output end of the first cylinder. A rack is provided on the slide rod corresponding to the position of each eccentric conveying roller mechanism, and a gear that meshes with the corresponding rack is fixed at one end of each eccentric conveying roller mechanism.

[0013] Furthermore, a pressing and conveying mechanism is also provided at one end of the discharge side of the frame. The pressing and conveying mechanism includes an active conveying roller, a rotation drive mechanism and a lifting drive mechanism that are driven and connected to the active conveying roller. The active conveying roller is located above the eccentric conveying roller mechanism.

[0014] Furthermore, the first driving mechanism includes a drive motor, the output end of which is driven to connect at least one worm gear transmission mechanism, the output end of each worm gear transmission mechanism is driven to connect a lead screw, the end of the lead screw away from the worm gear transmission mechanism is hinged to a connecting rod, the connecting rod is fixedly connected to at least one horizontal crossbar, the horizontal crossbar is provided with a vertical bar corresponding to the position of each lifting rod, and the horizontal crossbar is fixedly connected to the lifting rod through the corresponding vertical bar.

[0015] Furthermore, the second drive mechanism includes a second cylinder and a rotating rod. The rotating rod is rotatably connected to the frame through several bearings. A first connecting rod is hinged to one end of each first stop near the discharge side. A second connecting rod is hinged to one end of each first connecting rod away from the first stop. The end of each second connecting rod away from the first connecting rod is fixedly connected to the rotating rod. The output end of the second cylinder is hinged to one of the second connecting rods.

[0016] Furthermore, the stop block includes a top plane, and stop inclined surfaces are provided on both sides of the top plane.

[0017] Furthermore, each of the bearing rods and each of the lifting rods is provided with a blocking block at one end near the feeding side.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) By setting a lifting rod and a first stop rod, and the end of the lifting rod near the discharge side and the end of the first stop rod away from the discharge side are respectively hinged to the frame, when feeding is required, the second drive mechanism drives the first stop rod to rotate and lift, and the first drive mechanism drives the lifting rod to rotate and lift. During the lifting process, the lifting rod is higher than the bearing rod. The lifting rod lifts several long workpieces from the first horizontal section. At this time, the lifting rod is inclined. Several long workpieces move along the lifting rod towards the discharge side under the action of gravity. Since the lifting rod and the first stop rod are inclined in opposite directions, an angle is formed between the lifting rod and the first stop rod. The movement of several long workpieces is limited by the angle position. There is no need to use a stop baffle or other stop mechanism. This avoids the situation in the prior art where the stop baffle is used to block and limit the rolling large-diameter long workpieces, which causes the large-diameter long workpieces to have a large impact force on the stop baffle, which can easily cause damage to the stop baffle.

[0020] (2) By setting a stop block, when the sensor detects the first long workpiece and feeds back the detection signal to the control mechanism, and the control mechanism controls the first drive mechanism to drive the lifting rod to rotate and lower, since the position of the apex of the included angle is located on the side of the stop block closer to the discharge side, the bottom of the first long workpiece is supported between the stop block and the first stop rod. That is, the stop block and the first stop rod limit the first long workpiece, while the remaining long workpieces are re-supported on the support rod and located on the inclined section or the first horizontal section. The long workpieces located on the inclined section fall back to the first horizontal section due to gravity. That is, the separation between the first long workpiece and the remaining long workpieces is achieved. There is no need to use a lifting mechanism, which avoids the situation that the lifting is difficult and the lifting mechanism is easily damaged during the lifting and separation process, which requires overcoming the squeezing and frictional force of other long workpieces on the lifted long workpiece.

[0021] (3) By setting an eccentric conveying roller mechanism and a second stop, the third drive mechanism drives the eccentric conveying roller mechanism to rotate, thereby causing the second stop to swing between the clearance position and the blocking position. When the second stop is in the blocking position, the top of the roller is at its highest position. When the second stop is in the clearance position, the top of the roller is at its lowest position. By matching the position of the second stop with the horizontal height of the top of the roller, when several long workpieces roll from the feeding side to the discharging side, the second stop is in the clearance position and the top of the roller is at its lowest position, preventing the second stop from blocking the movement of the long workpieces and preventing the rolling long workpieces from impacting the roller. When the first long workpiece is separated, the second stop is in the blocking position and the top of the roller is at its highest position. On the one hand, the second stop is used to accurately position the first long workpiece, and on the other hand, it is convenient for the first long workpiece to be supported on the top of the roller, so that the bottom surface of the long workpiece is higher than the horizontal height of the workpiece bearing surface of the cutting platform. Even if the long workpiece is bent, its end can be smoothly entered into the cutting platform. Attached Figure Description

Detailed Implementation

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0031] like Figures 1 to 6As shown, Embodiment 1 provides an automatic material feeding and conveying system, including a control mechanism and a frame 1. The frame has an infeed side 11 and an outlet side 12 on its two sides. Multiple bearing rods 2 and multiple lifting rods 3 are spaced apart along the length of the frame 1. Multiple first stop rods 4, multiple eccentric conveying roller mechanisms 5, and at least one sensor are spaced apart along the length of the outlet side 12 of the frame 1. The end of each lifting rod 3 near the outlet side 12 and the end of each first stop rod 4 away from the outlet side 12 are hinged to the frame 1. A first drive mechanism 30 is connected to each of the lifting rods 3, which drives the lifting rods 3 to rotate around their hinged positions. The multiple first stop rods 4 are connected to... A second drive mechanism 40 is connected to drive a plurality of first stop rods 4 to rotate around their hinged positions; a second stop rod 6 is fixedly provided at one end of each eccentric conveying roller mechanism 5 near the feed side 11; a third drive mechanism 50 is connected to the plurality of eccentric conveying roller mechanisms 5, and the third drive mechanism 50 is used to drive the eccentric conveying roller mechanism 5 to rotate, thereby causing the second stop rod 6 to swing between the avoidance position and the blocking position; along the direction from the feed side 11 to the discharge side 12, the bearing rod 2 sequentially includes a first horizontal section 21, an inclined section 22 and a second horizontal section 23, the horizontal height of the second horizontal section 23 is higher than the horizontal height of the first horizontal section 21, wherein a blocking block 24 is provided at one end of the second horizontal section 23 near the inclined section 22.

[0032] Specifically, the bearing rod 2 is fixedly connected to the frame 1. When the first drive mechanism 30 and the second drive mechanism 40 are not in operation, the lifting rod 3 and the first stop rod 4 are in their initial positions. At this time, both the lifting rod 3 and the first stop rod 4 are horizontally set, and the horizontal height of the top of the lifting rod 3 is less than or equal to the horizontal height of the top of the first horizontal section 21, and the horizontal height of the top of the first stop rod 4 is less than or equal to the horizontal height of the top of the second horizontal section 23. When the third drive mechanism 50 drives the eccentric conveying roller mechanism 5 to rotate, thereby moving the second stop rod 6 to the clearance position, the second stop rod 6 is horizontally set and the top of the eccentric conveying roller mechanism 5 is at the lowest position. The second stop rod 6 will not obstruct the movement of the long workpiece. When the third drive mechanism 50 drives the eccentric conveying roller mechanism 5 to rotate, thereby moving the second stop rod 6 to the blocking position, the second stop rod 6 is vertically set and the top of the eccentric conveying roller mechanism 5 is at the highest position. The second stop rod 6 will obstruct the movement of the long workpiece, and the horizontal height of the top of the eccentric conveying roller mechanism 5 is higher than the horizontal height of the top of the second horizontal section 23.

[0033] In actual use, several long workpieces are placed on the first horizontal section 21 of the bearing rod 2 by an external feeding mechanism or manually. The control mechanism starts the feeding program. First, the third drive mechanism 50 drives the eccentric conveying roller mechanism 5 to rotate, thereby causing the second stop rod 6 to swing downward to the clearance position to avoid the second stop rod 6 from blocking the movement of the long workpieces. At the same time, the second drive mechanism 40 drives the first stop rod 4 to rotate and lift, thereby limiting the movement of the long workpieces by the first stop rod 4. Then, the first drive mechanism 30 drives the lifting rod 3 to rotate and lift. Because the lifting rod 3 and the first stop rod 4 are inclined in opposite directions, an angle is formed between them. The apex of the angle is located on the side of the stop block 24 closer to the discharge side 12. During the lifting process, the lifting rod 3 is higher than the bearing rod 2, and the lifting rod 3 lifts several long workpieces from the first horizontal section 21. Since the lifting rod 3 is inclined at this time, the several long workpieces move along the lifting rod 3 towards the discharge side 12 under the action of gravity. Then, when the one closest to the discharge side... When the first long workpiece (defined as the first long workpiece) moves to the included angle position, because the inclination direction of the first stop rod 4 is opposite to the inclination direction of the lifting rod 3, the first long workpiece will stop at the included angle position. At this time, the first long workpiece is supported at the included angle position, that is, the horizontal height of the bottom of the first long workpiece is higher than the horizontal height of the top of the supporting rod 2 and the eccentric conveying roller mechanism 5. Therefore, when several long workspieces move towards the discharge side 12, they will not collide with the supporting rod 2 and the eccentric conveying roller mechanism 5, preventing the bearing... The carrier rod 2 and the eccentric conveying roller mechanism 5 are damaged. At this time, due to the blocking effect of the first long workpiece, the remaining long workpieces also stop moving forward. That is, the movement of several long workpieces is limited by the opposite angle formed by the tilting directions of the lifting rod 3 and the first stop rod 4. There is no need to use a stop baffle or other stopping mechanism. This avoids the situation in the prior art where a stop baffle is used to block and limit the rolling large-diameter long workpiece, which causes the large-diameter long workpiece to generate a large impact force on the stop baffle, thus easily causing damage to the stop baffle.Next, the sensor detects the first long workpiece and feeds back the detection signal to the control mechanism. The control mechanism controls the first drive mechanism 30 to drive the lifting rod 3 to rotate and lower. When the lifting rod 3 rotates to the initial position, it is horizontal and the horizontal height of the top of the lifting rod 3 is less than or equal to the horizontal height of the top of the first horizontal section 21. Since the position of the apex of the included angle is located on the side of the stop block 24 near the discharge side 12, the bottom of the first long workpiece is supported between the stop block 24 and the first stop rod 4. That is, the stop block 24 and the first stop rod 4 limit the first long workpiece, while the remaining long workpieces are supported again on the support rod 2 and located on the inclined section 22 or the first horizontal section 21. The long workpiece on the inclined section 22 falls back onto the first horizontal section 21 due to gravity, thus separating the first long workpiece from the others. This eliminates the need for a lifting mechanism, avoiding the need to overcome the squeezing and frictional forces of other long workpieces on the lifted workpiece during the lifting and separation process, which would otherwise make lifting difficult and prone to damage. Next, the third drive mechanism 50 drives the eccentric conveyor roller mechanism 5 to rotate, causing the second stop rod 6 to swing upwards to the stop position. At this point, the top of the eccentric conveyor roller mechanism 5 is higher than the horizontal height of the second horizontal section 23, and the second stop rod 6 precisely positions the first long workpiece, ensuring... The positioning accuracy of the first long workpiece during subsequent conveying is ensured; then, the second drive mechanism 40 drives the first stop 4 to rotate and lower, while the first long workpiece descends to the top of the multiple eccentric conveying roller mechanisms 5 during the rotation and lowering of the first stop; finally, the first long workpiece is conveyed along the eccentric conveying roller mechanism 5 to the next processing station, thus completing the automatic material distribution and conveying of a long workpiece; specifically, the next processing station is the cutting station. To avoid the long workpiece bending and the end of the long workpiece being unable to smoothly enter the cutting platform, the horizontal height of the workpiece bearing surface of the cutting platform is lower than the horizontal height when the top of the eccentric conveying roller mechanism 5 is at its highest position. The workpiece is supported on the eccentric conveyor roller mechanism 5, ensuring that the horizontal height of the bottom surface of the long workpiece is higher than the horizontal height of the workpiece bearing surface of the cutting platform. Even if the long workpiece bends, its end can smoothly enter the cutting platform. Furthermore, the horizontal height of the workpiece bearing surface of the cutting platform is higher than or equal to the horizontal height of the top of the eccentric conveyor roller mechanism 5 when it is at its lowest position. Once the end of the long workpiece has smoothly entered the cutting platform, the third drive mechanism 50 is controlled to drive the eccentric conveyor roller mechanism 5 to rotate, thereby lowering the horizontal height of the top of the eccentric conveyor roller mechanism 5 to match the horizontal height of the workpiece bearing surface of the cutting platform. This ensures that the cut surface formed on the long workpiece during subsequent cutting is a vertical plane.

[0034] More specifically, the eccentric conveying roller mechanism 5 includes a rotating shaft 51, two support seats 52, two eccentric bearings 53, and a roller 54. The two support seats 52 are spaced apart on the discharge side 12 of the frame 1. The two ends of the rotating shaft 51 are rotatably mounted in the two support seats 52, and one end of the rotating shaft 51 passes through the corresponding support seat 52 and is driven and connected to the third drive mechanism 50. The two eccentric bearings 53 are fixedly mounted on the rotating shaft 51 and located between the two support seats 52. The two ends of the roller 54 are respectively sleeved on the two eccentric bearings 53. In this embodiment, on the one hand, the position of the eccentric bearings 53 is adjusted by driving the rotating shaft 51 to rotate through the third drive mechanism 50, thereby adjusting the horizontal height of the top of the eccentric conveying roller mechanism 5. On the other hand, the two ends of the roller 54 are sleeved on the eccentric bearings 53. When the long workpiece is conveyed to the next processing station, the roller 54 rotates with the long workpiece, effectively reducing the frictional resistance during the conveying process of the long workpiece.

[0035] More specifically, the second stop rod 6 is fixedly connected to the end of the rotating shaft 51 near the feed side 11 and is located between the roller 54 and the support seat 52; when the second stop rod 6 is in the material blocking position, the top of the roller 54 is at its highest position, and when the second stop rod 6 is in the clearance position, the top of the roller 54 is at its lowest position. Specifically, the end of the rotating shaft 51 near the feed side 11 is provided with a connecting through hole, and the second stop rod 6 is inserted into the connecting through hole. In this embodiment, the position of the second stop 6 is matched with the horizontal height of the top of the roller 54. When several long workpieces roll from the feeding side to the discharging side, the second stop 6 is in the clearance position and the top of the roller 54 is in the lowest position, preventing the second stop 6 from blocking the movement of the long workpieces and preventing the rolling long workpieces from impacting the roller 54. When the first long workpiece is separated, the second stop 6 is in the blocking position and the top of the roller 54 is in the highest position. On the one hand, the second stop 6 accurately positions the first long workpiece, and on the other hand, it facilitates the first long workpiece to be supported on the top of the roller 54, so that the bottom surface of the long workpiece is higher than the horizontal height of the workpiece bearing surface of the cutting platform. Even if the long workpiece bends, its end can be smoothly entered into the cutting platform.

[0036] More specifically, the third drive mechanism 50 includes a first cylinder 501 and a slide rod 502 connected to the output end of the first cylinder 501. A rack 503 is provided on the slide rod 502 corresponding to the position of each eccentric conveying roller mechanism 5. One end of each eccentric conveying roller mechanism 5 is fixed with a gear 504 that meshes with the corresponding rack 503. In this embodiment, only one first cylinder 501 is needed to drive multiple eccentric conveying roller mechanisms 5 to rotate synchronously, resulting in a simple structure and low cost.

[0037] More specifically, a pressing and conveying mechanism 8 is also provided at one end of the discharge side 12 of the frame 1. The pressing and conveying mechanism 8 includes an active conveying roller 81, a rotation drive mechanism and a lifting drive mechanism 82 that are driven and connected to the active conveying roller 81. The active conveying roller 81 is located above the eccentric conveying roller mechanism 5. Specifically, it also includes a fixed frame 83, on which the active conveying roller 81, the rotation drive mechanism and the lifting drive mechanism 82 are all mounted. In this embodiment, when the first long workpiece descends to the top of the multiple eccentric conveying roller mechanisms 5 during the rotation and lowering of the first stop 4, the lifting drive mechanism 82 drives the active conveying roller 81 to press down to the top of the first long workpiece, and the rotation drive mechanism drives the active conveying roller 81 to rotate, thereby conveying the first long workpiece to the next processing station.

[0038] More specifically, the first driving mechanism 30 includes a driving motor 301. The output end of the driving motor 301 is driven and connected to at least one worm gear transmission mechanism 302. The output end of each worm gear transmission mechanism 302 is driven and connected to a lead screw 303. The end of the lead screw 303 away from the worm gear transmission mechanism 302 is hinged to a connecting rod 304. The connecting rod 304 is fixedly connected to at least one horizontal crossbar 305. The horizontal crossbar 305 is provided with a vertical bar 306 corresponding to the position of each lifting rod 3. The horizontal crossbar 305 is fixedly connected to the lifting rod 3 through the corresponding vertical bar 306. Specifically, two worm gear transmission mechanisms 302 are provided, and the two worm gear transmission mechanisms 302 are connected by a linkage mechanism. The drive motor 301 drives the two worm gear transmission mechanisms 302 to move synchronously, thereby driving the two lead screws 303 to rise and fall synchronously. Then, through the connecting rod 304, the horizontal bar 305 and the vertical bar 306, multiple lifting rods 3 are driven to rotate around their respective hinge positions.

[0039] More specifically, the second drive mechanism 40 includes a second cylinder 401 and a rotating rod 402. The rotating rod 402 is rotatably connected to the frame 1 via several bearings 403. Each first stop rod 4 has a first connecting rod 404 hinged to one end near the discharge side 12. Each first connecting rod 404 has a second connecting rod 405 hinged to one end away from the first stop rod 4. Each second connecting rod 405 has a fixed connection to the rotating rod 402 at one end away from the first connecting rod 404. The output end of the second cylinder 401 is hinged to one of the second connecting rods 405. In this embodiment, the second cylinder 401 extends and drives the second connecting rod 405 hinged to it to rotate. The rotation of the second connecting rod 405 drives the rotating rod 402 to rotate, which in turn drives the remaining second connecting rods 405 to rotate. Then, through the first connecting rods 404, multiple first stop rods 4 rotate around their respective hinged positions. By setting one second cylinder 401, multiple first stop rods 4 can be driven to rotate, resulting in a simple structure and low cost.

[0040] More specifically, the baffle block 24 includes a top plane 241, and baffle ramps 242 are provided on both sides of the top plane 241. In this embodiment, by setting the baffle ramps 242, when the control mechanism controls the first drive mechanism 30 to drive the lifting rod 3 to rotate and lower, the baffle ramp 242 on the baffle block 24 near the discharge side forms a second angle with the first baffle rod 4. At this time, the second angle limits the first long workpiece, preventing the first long workpiece from falling back onto the first horizontal section 21, thus realizing the separation between the first long workpiece and the other long workpieces.

[0041] More specifically, each of the bearing rods 2 and each of the lifting rods 3 is provided with a blocking block 7 at one end near the feeding side 11. In this embodiment, by providing the blocking block 7, when a long workpiece located on the inclined section 22 falls back to the first horizontal section 21 due to gravity, the blocking block 7 can limit the long workpiece and prevent it from rolling out of the first horizontal section 21.

[0042] The automatic material sorting and conveying method using the automatic material sorting and conveying system described in any of the above embodiments specifically includes the following steps:

[0043] S1: The first horizontal section 21 of the bearing rod 2 carries several long workpieces, among which the long workpiece closest to the discharge side 12 is the first long workpiece. The control mechanism starts the feeding program, and the third drive mechanism 50 drives the eccentric conveying roller mechanism 5 to rotate, thereby driving the second stop rod 6 to swing down to the clearance position. At the same time, the second drive mechanism 40 drives the first stop rod 4 to rotate and lift.

[0044] S2: The first driving mechanism 30 drives the lifting rod 3 to rotate and lift, so that the lifting rod 3 and the first stop rod 4 form an angle, and several long workpieces move along the lifting rod 3 towards the discharge side 12 during the rotation and lifting of the lifting rod 3.

[0045] S3: When the first long workpiece moves to the included angle position, the sensor detects the first long workpiece and feeds back the detection signal to the control mechanism. The control mechanism controls the first drive mechanism 30 to drive the lifting rod 3 to rotate and lower. When the lifting rod 3 rotates to the initial position, the first long workpiece is supported between the stop block 24 and the first stop rod 4. The remaining long workpieces are supported again on the support rod 2 and located on the inclined section 22 or the first horizontal section 21. The long workpieces located on the inclined section 22 fall back to the first horizontal section 21 due to gravity.

[0046] S4: The third driving mechanism 50 drives the eccentric conveying roller mechanism 5 to rotate, thereby causing the second stop 6 to swing upward to the stop position. At this time, the horizontal height of the top of the eccentric conveying roller mechanism 5 is higher than the horizontal height of the second horizontal section 23. Then the second driving mechanism 40 drives the first stop 4 to rotate and lower.
